When adding a component whose dialog has an editCode control with useCodeHighlighter set to true (or not set, since true is the default in this case), a NullPointerException is thrown. Editing an existing component works fine.

To reproduce: on demo, change STK's stkHTML dialog so that its editHTML control is of type editCode (it's shipped as "edit", which is not impacted by this bug). Try to add a component of type "HTML" to a page. Boom.

I was able to reproduce this on 4.4.5 (on our docu site) and 4.5.3 (on the demo site)

Exception as thrown in 4.4.5:

java.lang.NullPointerException
	info.magnolia.cms.gui.dialog.DialogEditCode.drawEditorWithSyntaxHighligher(DialogEditCode.java:153)
	info.magnolia.cms.gui.dialog.DialogEditCode.drawHtml(DialogEditCode.java:133)
	info.magnolia.cms.gui.dialog.DialogControlImpl.drawSubs(DialogControlImpl.java:321)

Workarounds:

• don't use editCode
• set useCodeHighlighter to false (which essentially boils down to the same)

Diagnostic:
As far as I can tell, the bug is happening in DialogEditCode#drawEditorWithSyntaxHighligher, where we call getStorageNode(), which doesn't exist yet when creating a new component. (perhaps a side-effect of some of the content api changes in 4.3 ?)
